How do you appreciate the relation between magnetic field and electricity that changed the life style of mankind?
Answer :
The interaction between electricity and magnetism is called the electromagnetism and this relation has changed the lifestyle of the mankind in the following ways:
1. Electromagnets = placing iron bar inside the coil of wire and passing the current makes an electromagnet. It is 100 times powerful than a normal magnet. And is used to lift heavy weights. As shown in the figure.
2. Electric motors = The rotation of the coil due to the magnetic field generated mechanical energy which can be used in many forms. Like in Mixers, Water pump etc.
3. Electromagnetic radiation = magnetic fields and electric current makes waves which are called as electromagnetic radiation. These are used in X-ray.
